Tartan? & construction query?

[Lady Grey]

Another op-shop find. Does anyone recognize the tartan & manufacturer?
I like the colours & it had a deep hem otherwise I'm not impressed with the construction and have some questions for those more knowledgable.
- approx late '60's early '70's by my guess (threads, stitch length, press studs, etc)
-box pleated, darts in the aprons... I think made for a teenage girl.
- it has the usual home sewn repairs to small rips & tears as would be expected.
-however the construction is rather shabby and not consistent.
Did kilt makers use domestic outsourcing for their garments?
Would different sections of construction be sent out to different sewers?
The sewing of the pleats is different to the darts, the fringe is sewn differently to the waistband,etc, etc. different threads, some industrial some domestic, different hand sewing, different techniques used throughout.
Hope someone can help?
